  • Patent number: 8484843
    Abstract: A method for producing a dispersion-hardened object which contains carbide nanoparticles comprises producing an object by means of a thermal spraying method, wherein downstream of the combustion chamber, the gas flow is supplied by means of a carrier gas with at least one precursor which reacts in the gas flow to form a carbide, or carbide nanoparticles are supplied via an external nanoparticle generator which is subject to a thermal load. It allows the production of a dispersion-hardened object such as, for example, a component for an internal combustion engine, for example a piston ring. The method is carried out by means of a thermal spraying device which, downstream of the combustion chamber, besides at least one line for supplying a thermal spray powder, further comprises at least one line for supplying a precursor by means of a carrier gas.

  • Patent number: 8475944
    Abstract: A coated ceramic cutting insert for removing material from a workpiece, as well as a method for making the same, that includes a ceramic substrate with a rake surface and at least one flank surface wherein a cutting edge is at the juncture therebetween. A wear-resistant coating scheme that includes an alumina-containing base coating layer region, which has at least one exposed alumina coating layer, deposited by chemical vapor deposition on the substantially all of the surfaces of the ceramic substrate that experience wear during removal of material from the workpiece. The exposed alumina coating layer exhibits a blasted stress condition ranging between about 50 MPa (tensile stress) and about ?2 GPa (compressive) as measured by XRD using the Psi tilt method and the (024) reflection of alumina. The exposed alumina coating layer is the result of wet blasting a titanium-containing outer coating layer region from the surface of the alumina-containing base coating layer region.
